Does what it says! Rated 5 out of 5 stars
There were people complaining that it hides the tab contents, without hiding the tab itself. This is exactly what this extension is supposed to do, and it does it well. As regards displaying the contents of the paused tab, how do you expect Firefox to do this while freeing the memory? It is simply in the nature of this extension that it can not display the contents when it unloads them from memory. A possibly improvement might be an option to generate a small preview image (which would take less memory) for clarity.This review is for a previous version of the add-on (1.0.4).
